BOTTLE.

To all whom it may concern:

Be it known that I, JAMES C. ANDERSON, a citizen of the United States,residing at Washington city, in the District of Columbia, have inventedcertain new and useful Improvements in Bottles; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to certain new and useful improvements in bottlesof that class in which the closure is effected by means of a sheet metalcap secured in removable relation with the neck of the bottle.

In the type of bottles referred to, the neck is generally provided atits upper extremity with an exterior rib and the sheet metal cap issecured in position by crimping it upon the exterior rib on the bottle,the projecting portion of the crimps or corrugations being adapted toreceive a suitable tool employed to remove the cap when desired. Bottlesof the type referred to have also been made with depressions in theinterior surface of the neck at its upper extremity and inverted caps orcups of sheet metal placed within the neck and expanded within theannular recess of the same. Bottles of this last described type havealso been provided with a secondary sheet metal cap crimped or otherwisesecured upon an annular rib on the outer surface of the neck andcovering and concealing the interior cup-shaped device. In the firstnamed type a disk, or a ring-shaped gasket is interposed between the capand the upper end of the neck of the bottle and in the other describedtypes a packing or gasket is located between the side walls of the capand the cylindrical surface of the bottle.

My invention relates particularly to that type in which the cap iscompressed against the inner wall of the bottle neck and it has for itsobject to dispense entirely with any recesses or depressions in thesurface of the glass, which recessesor depressions render it more orless difficult to cleanse the bottle after the contents have beenremoved; also to reduce to a minimum any liability to fracture thebottle in applying the cap and also to render the air and gas-tightjoint between the bottle and cap constant and more ef.

fective.

describe the same referring by numerals to g the accompanying drawing inwhich Figure lis a central vertical section of the neck of a bottleembodying one of the features of my invention. Fig. 2 is a centralvertical section of my improved cap. Fig. 3 is a similar section showingthe cap and bottle in proper relation for securing the cap in place, andwith the sealing gasket located between the cap and bottle neck, andFig. 4-. is a similar view showing the relation of parts after the caphas been secured in air and gastight position.

Similar reference numerals indicate like parts in the several figures ofthe drawing.

' 1, is the neck of the bottle which as will be seen is so formed on itsinner surface that it is of smaller diameter at its upper extremity thanbelow that locality, or in other words is tapered toward the extremitythus producing a form with which the sheet metal cap pression of thecentral portion necessarily produces an interior wall. 3, adapted to beexpanded into close contact with the interior surface of the bottleneck. The remaining outer portion or rim 4, of the cap is of a formcorresponding substantially with that of the upper extremity of the neckas clearly shown.

and extending in a vertical direction below the longest radius of theexterior rib 5, on the bottle neck as indicated at 6, to constitutemeans by which the cap when desired.

7, is a gasket of soft metal or other suitable compressible materialconforming with the inner wall 3, and rim 4, and constituting as will beobvious, a continuous sealing joint with the inner upper and outersurfaces of the bottle and also the upper extremity and thus providingan effective closure.

The cap 2, has its bottom formed concave as shown at 8, and is providedwith an independent convex sheet metal disk 9, or the bottom of the capmay be convex and the may be removed disk concave as fully described andshown in another application filed by me on even date herewith andhaving Serial No. 378,544.

In applying my improved cap to the improved bottle, the cap is locatedas shown at Fig. 3, with its central depressed portion entering thebottle neck and with its rim resting upon the upper extremity of thebottle and with the extreme outer portion 7, extending vertically belowthe exterior rib 2, of the bottle.

The interior vertical wall 3, is at its upper extremity substantially incontact with the extreme inner surface of the bottle neck while theremainder of the wall 3, of the cap is a slight distance therefrom asclearly shown. The gasket 7, surrounds the upper extremity as clearlyshown and when the cap is secured in position as shown at Fig. 4, theinner vertical wall is expanded by the force exerted upon theindependent disk 9, into close relation with the converging terminus ofthe bottle neck while the rim portion 4, with the exception of itsvertical terminus tightly embraces the upper extremity of the bottle,the gasket 7, being tightly compressed and making a close air andgas-tight joint throughout its entire extent.

During the operation described the concaved central portion 8, of thecap being of greater area than the cross section of the cylindricaldepressed portion compensates for the outward movement of the verticalwall 3, and this action takes place whether the bottom of the cap isconcave, and the expanding disk 9, is convex as shown, or the reverserespectively, as shown and described in the copending applicationhereinbefore referred to, and as the bottom in either case isnecessarily under strain as the side wall 3, is expanded toward thebottle neck it operates to restrain and prevent any sudden and excessivemovement of the wall tending to the fracture of the bottle neck, andexerts a pulling action which draws the outer rim portion 4,coincidently toward the outer surface so that at the time when the wall3, is being forced into such contact as to compress the soft metalgasket 7, equal pressure is being exerted on the opposite surfaces ofthe bottle neck. I however prefer the form herein shown, for the reasonthat after the cap has been permanently aflixed to the bottle there willstill remain a slight concavity in the bottom and if the contents of thebottle be of a gaseous nature the force exerted against the bottom bysuch gases will have the effect of keeping the joint between the wall 3,of the cap and the bottle tight and continuous.

Particular attention is called to the fact that the convergence of theinner surface of the bottle neck toward its extremity while providing asurface with which the wall 3, of the cap may be securely interlocked,avoids the presence of any abrupt projection or re cess which wouldretard or render ineffective the effort to cleanse the bottle for reuse.

Another important feature of my invention resides in the fact that whenthe wall 3, of the cap is being forced into close contact with the innersurface of the bottle, the outer I arc of the rim at, beingsubstantially in contact with the corresponding part of the bottleserves as a brace to protect the bottle neck from accidental fracturewhich might otherwise take place, and which frequently occurs especiallyin that type of bottles in which the cap is secured by pressure exertedupon the outside of the cap.

It will be seen that as a result of the construction of the cap 2, withits vertical terminal 7, that when the cap is removed from the bottleand the lower extremity of the inner wall 3, consequently forced inward,the cap may then be used as an ordinary cover to protect any contentsremaining in the bottle.

As stated hereinbefore I prefer to make the tapered surface of thebottle neck, substantially as hereinbefore set forth.

2. In combination with a bottle having the inner surface of the neckterminating in an unbroken upward taper, a sheet metal cap embracing theouter surface and upper ex tremity of the bottle neck and interlockedwith the inner converging extremity thereof, substantially ashereinbefore set forth.

3. In combination with a bottle having the interior surface of the neckterminating in an unbroken upward taper, and having an annular rib onthe outer extremity; a sheet metal cap having a depressed centralportion secured in sealed relation with the inner upwardly taperedextremity of the bottle neck and an outer rim portion embracing theexterior rib on the bottle neck and extending vertically below the same,substantially as and for the purpose set forth.

4. In combination with a bottle having the inner surface of the neckterminating in an unbroken upward taper and a sheet metal cap formedwith a central depressed portion adapted to enter the neck of the bottleand to be expanded against the converging tapered surface thereof andhaving a lateral and vertical rim; a soft metal gasket interposedbetween the sheet metal cap and the inner and outer surfaces of thebottle neck, substantially as and for the purpose set forth.

5. In combination with a bottlelhavingthe interior surface of the neckterminating in an unbroken upward taper and having on its exteriorextremity a circumferential rib; a sheet metal cap secured in air andliquid tight relation with the interior tapered surface of the bottleand having an overhanging rim extending in a vertical line below thecircumferential rib, substantially as and for the purpose set forth.

6. In combination with a bottle having the interior surface of the neckterminating in an unbroken upward taper, and a sheet metal closuredevice open at its outer end and closed at its opposite end by anintegral eX- pansible bottom; an independent expansible sheet metal diskadjacent to the bottom of the closure device and adapted to cooperatetherewith to hold the wall of the same in close and constant contactwith the interior surface of the neck of the bottle, substantially ashereinbefore set forth.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribingwitnesses.
